8 Claims.

My invention relates to a distributing chute for use with transit concrete mixers and has particular reference to a chute which is normally carried upon the truck chassis at the side of the drum and which can be easily and quickly swung into position at the rear of the drum to receive concrete discharged from the drum and deposit it at ground level for use in making a oor, roadway, sidewalk or the like, or the chute can be so positioned that the concrete is discharged into a bucket positioned above the ground level or into some other form or type of conveyer or into forms. And when used either way can be moved in an arcuate path at the rear of the drum whereby the concrete mix is distributed over a specied area.

Another and further object of my invention is the provision of a discharge chute comprising two sections of diiferent lengths which are nested together adjacent the discharge end of the drum and mounted at their rear ends upon a movably mounted frame which supports one end of each of the chute sections in both its operative and linoperative positions and in which the short section of the chute is permanently secured upon the frame and may be used independently of the other section or it may be used as a mounting member for the longer section where the concrete mix is to be deposited at a greater distance from the transit truck.

Another and further object of my invention is the provision of a distributing chute comprising sections which in normal operation are easily and quickly locked together for transport purposes and the like, but which can easily be separated and swung into position for receiving concrete discharged from the end of the drum and conveying it to a point adjacent the ground or into a housing, bucket or form or the like positioned either above the ground, at the ground level, or below ground if desired, the parts being so arranged that they can be separated and easily manipulated into position for use in delivering the concrete a short distance away from the discharge chute or for a longer distance away, depending upon the necessities of the situation.

Another and further object of my invention is the provision of a concrete delivery chute which is so mounted and arranged that the concrete mix discharged from the drum can be delivered throughout an area of a little over 180 in circumference in the area adjacent the rear or discharge end of the mixing drum.

Another and further object of my invention is the provision of a discharge chute which can be easily and quickly placed in position to receive concrete mix discharged from the drum and likewise easily and quickly secured in position at the side of the drum for transport purposes without material effort on the part of the operator, thus resulting in time saving which is an essential element in the operation of these transit trucks.

These and other objects of my invention will be more readily and better understood by reference to the accompanying drawings in which:

Fig. 1 is a side elevational View of the rear end of a transit mixer with my improved distributing chute mounted thereon.

Fig. 2 is a rear elevational view of a mixing drum and mounting therefor on a truck chassis showing the distributing chute in inoperative position.

Fig. 3 is a perspective View of the discharge end of a mixing drum showing the distributing chute in operative position.

Fig. e is a perspective viewfof the distributing chute alone, showing the parts in nested relation with each other.

Fig. 5 is a view similar to Fig. 4 but showing the sections of the distributing chute in partially separated condition.

Fig. 6 is a perspective View similar to Fig. 5 except that the sections of the chute are shown in completely separated positions.

Fig. 7 is a perspective View of the chute showing the sections separated, the shorter section being in operative position.

Referring now specically to the drawings and in which like reference characters refer to like parts throughout, a mixing drum Il) is shown of the usual form of concrete mixers except perhaps somewhat more elongated having an open rear end Il with a ring l2 .around the body of the drum at the rear end thereof. A track I3 extends circumferentially around the drum intermediate its ends and is in engagement with rollers i4 mounted in blocks I5 which in turn are mounted upon a pillow block i6 supported upon a frame l1 which is secured to the chasis I8 of the usual truck. The frame I1 has a cross member I9 at the rear end thereof to which the lower ends of a yoke 20 are secured, the yoke 2d having a charging chute 2| mounted thereon and secured to the upper end Ythereof with braces 22, 22 being provided which are secured to the yoke 29 at one of their ends and to the charging chute 2| at their opposite ends. A V-shaped gathering chute 23 is provided which has a discharge opening 24 in the bottom thereof,

with each of the sides of the chute 23 being semi-circular in cross section, the chute 23 being mounted below the opening H in the rear end of the drum I and is held in position by a cross brace secured at each of its ends to the sides of the yoke 20. A plurality of side braces 26, 26 are provided oni each side of the drum Ii! and which are secured at their rear ends to the yoke 2G and at their forward ends to the pillow block I6 and to a cross member 21 mounted upon the pillow block i5. A pair of diagonally extending cross braces 28V and 29 are provided which are secured at each of their ends to the side members of the yoke 2i! and cross. each other at right angles at their centers` thereby forming a diagonal bracing means for the yoke 2). At the bottom of the yoke .20 a cross inember 3i? is provided which further braces the yoke 20 and forms a support for the distributing chute as will be more fully described hereinafter.

The distributing chute consists. of a short section 3| which may be used as. a chute .tor carryw ing` the discharged.. concrete mix,. or as a mounting and. holding section for a longer chute, hereinafter described and which is semi-circular in cross section andY which has flanges 32` and 33 along each ot its marginal edges which are either welded to or may be integrally formed with the body of the chute 3l with a closure member 3 at the end of the chute 3| adjacent the gathering chute 23. Semi-circular saddle members. 35 and 36 are formed upon which the chute 3i is mounted, these saddle members having ears 3T, 3i at the lower sides thereof and have extended upper ends 38, 38'which. project slightly above the flanges 32 and 33 of the chute 3l, these end portions 38 having notches 39, 3S therein for purposes hereinafter described.

The section 3| is mounted upon a movably mounted framey at the rear end ot the drum I3 comprising a vertical .member de, horizontal members 4i and 42 which. are secured to the member to at one of their ends adjacent the upper and lower ends ofthe member to with a cross brace .43 being provided which is secured at its lower end to the member 42 .and at its upper end to the member M. A rod M is secured at its upper end to the diagonalV brace 28 by means of' a fastening `member 45, to the cross brace 35 by another fastening member t5, and at its lower end to the crossv member i9 by means of another fastening member' liso that the frame carrying the section 31 isipivotally mounted upon the rod i4 so that when the frame is swung outward, the chute section 3i is in position to be mounted at the side of: the truck in inoperative position and when turned inwardly the upper end* of the chute' section 31' is positioned under thedischarge opening' 2d vof the gathering chute 23. Co-operating locking members (not shown) are usually mounted on the braces 42 and 43' and braces 2e and 3o which permit thei'rame and chute si from swinging` away from under the gathering chute 23.

A rotatable axle 48 is mounted in the frame` member 4U and has a trunnion i9 at the upper end thereof which projects between the ears 31, 3T onY the saddle memberV 35 and has a pin 53 extending through the trunnion ce and the ears 3?, 3? which provides a mounting for the upper end of the chute section 3| on the frame member e with a bracket' 5i being provided which is mounted upon the lower end of the axle 48,. with. a hydraulic jack 52` mounted on the bracket 5l. with a plunger 53 projecting therefrom and an of' my present invention.

4 operating rod 54 mounted in the plunger 53 which has a connecting member 55 thereon and which extends between the ears 31, 3l on the saddle 36 adjacent the outer end of the chute section 3l and is secured to these trunnions by means of a pin 5t. An operating handle 51 is mounted upon the jack. 52v which is an.- ordinary hydraulic two way jackY and provides means by which the section 3l of the chute can be raised and lowered. A second chute section 53 is provided which has a body portion semi-circular in cross section andi with flanges 59 and Si) at each side thereof with reinforcing plates 6l, @i being provided having openings 8-2, '52 therein which are so Aspaced that when the section 58 of the discharge chute is properly nested in the section 3| the projecting ends 38 of the saddle members 35 and 35 project through the openings 62, t2 in the reinforcing members 5I, 3| and a slight downward longitudinal movement ot the chute 58 will lock the two. sections. v3 I. and. 58 of the chute together in substantially a unitary structure for mounting, on the truck in inoperative position and also for use in operative position when it is desired to convey the concrete mix a greater distance away from the discharge end of the mixing drum than what can. be accomplished with the short section 3T ofthe discharge chute. The section. 53 is of substantially the same construction as the chutey 3L but is longer by several feet than is the short section The lengths of each of the chute sections will vary depending upon the capacity and size ofthe drum, but as now used by me, I' und that a length of ve feet is suitable for the section 3l' and about twelve feet for the section 58.

A front pillow block 63 is provided upon which a bracket 64 is mounted which 'forms a bearing for an axle 65 which is securedito the front end o the drum min any approved manner with a sprocket wheel 6B being provided over which a sprocket chain. 61 is mounted, leading to suitable power apparatus. for rotating the drum it in the operation of .the device but which forms' no part A bracket E3' is secured to the side of the pillow'block' 63 and has a pin Se projecting therefrom which projects through an ear til forming a continuation of a saddle 'H at the lower end of the chute 58 with a removable key 12' in through theA pin 69 to hold the lower end of the chute 53 in position alongside of the druml I0.

The bracket 2T carries a hinged support member 'i3' having a hole T4 therein through which the end of an L-'shaped lug-15 extends which is secured to the bottom of' the section 58 and has a key TS in the outer end of the lug T5 so the support 13 is held in position when it is supporting the section 58 as shown in Figs. 6 and 'Z of the drawings.

When it is desired to loperate thechute, includa ing the long section 53, and assuming that it is mounted upon the transitmi'xer 1, the operator removes the key T2 and through the use of the jack 52 by operating the handle 51 the chute sections 3d' and 53 are lifted a slight distance and then manually turned into position so that the frame on which the distributing chute is mounted brought` to central position ci the drum liand the upper ends. of` both chutes under the. discharge-opening 2A in the collecting chute 23. so that'the two nested chutes areready to receive the concrete mix which is discharged from the open end ofthe drum lli. `When in this position, the frame is llocked into position to the as shown in Fig. Y

cross brace 29 by any latching or common fastening means thereby holding the chute frame and chutes in fixed position. The operator, by moving the chute 58 normally in an arcuate path can cause the concrete mix to be deposited adjacent the ground or into a receptacle such as might be desirable in building a roadway, approach to a garage or the like with the operator regulating the height of the chute 58 above the ground to whatever distance may be desirable depending upon the kind and character of the work. When the load from the drum I9 is discharged, the operator removes the key 'I8 thereby returning the frame in which the chutes are mounted and swings the frame and chute radially into a position alongside of the transit mixer as shown in Figs. 1 and 2 and locks the end of the chute 58 over the pin 69 regulating the height of the chute by means of the jack so that the chute is thereupon in position to be transported alongside of the transit mixer while the transit mixer is returning to a central location for an additional lading of concrete mix.

Assuming that on the next discharge, only the short section 3| of the chute is necessary, the operator releases the chute 58 from the pin 69 as heretofore described and moves the chute 58 longitudinally to a pointl where the reinforcing members 6I 6l are out of engagement with the hooked projecting ends 38, 38 of the saddle members 35 and 35 and elevates the two chutes slightly by means of the jack and turns the support member 'F3 into position under the chute section 58 as shown particularly in Fig. 5. With the chute section 58 supported on the central support member 13 the outer end of the short chute 3i is lowered so that it is free of the chute 58 and the operator thereupon manually turns it free of the chute 58 as shown in Fig. 6 when the operator can manually rotate the section 3| and frame on which it is mounted, including the jack, to a position where the upper end of this chute 3! is under the discharge opening 24 in jacking chute 23 with the chute frames in position as hereinabove described so that the chute while in this position is held against rotative movement. The operator A' through the use of the jack can raise or lower the outer end of the section 3l to any height desired for depositing concrete into a hoisting bucket,

form, or the like and can, of course, move the chute 3'! normally through a semi-circular area in the rear of the drum while the section 58 remains in inoperative position mounted at the side of the truck as shown particularly in Fig. 7. When the lading has been discharged through the short section 3| and the operator desires to nest the two sections together, the section 3| is returned to a position horizontal with the section 58 and shown particularly in Fig. 6, the free end is elevated so that the projected ends pass through the opening 62 in the plate 6I, the support member 13 is turned to dotted position as shown particularly in Fig. and the chute is lowered to a position which nests the two chutes together and then by an outward longitudinal movement of the chute 58 the two sections are locked together by the engagement of the locked end of the saddles 35 and 35 over the plate 6| and the chute again locked in position over the pin 69 as heretofore described when the chute can be transported along with the chassis to any desired point or direction.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I conwithout departing from the spirit or scope of my invention.
